The bracelets are basically ribbed flat plates, which are bend around.
I don't believe these are cast in curved from. Therefore I decided to cast
them flat, and bend them later. The mould is made from two flat plates
of clay, one I carved the shape in after it was half dry.

Casting result

This type of bracelet I've cast before, in another mould.
The previous example was too wide and too thick, and had a too high tin
content. Especially because of the latter it was almost impossible to bend,
and broke during bending. This time I adjusted the dimensions of the mould
and used a lower tin content, around 10%. Lower then that is not prefered,
as then it will become dull brown too quickly when worn. It's an ornament,
so it has to shine as much as possible! The result so far is two succesful
castings. I still have to wait to see if they survive the bending, but
at least the bronze is a lot more ductile.

Finished bracelets

Here are the finished bracelets, including a third casting.
For this, modern tools were used. After finishing, the bracelets were bend
round.
